I am using capstone-3.0.4 on ubuntu 18.04. After installing all the required tools needed for running multiverse, I got the following message during disassembly.

As the README says, we use a modified version of Capstone to rewrite 64-bit binaries. Please try rewriting with that version.

While I would like to update Multiverse to work with the most recent version of Capstone, I need access to certain data about instruction encodings for 64-bit binaries (specifically the offset and size of displacements and immediates in instructions). These fields were not accessible in Capstone at the time, which is why I made a fork.

If or when this changes and the data I need is provided to the python bindings it should not be difficult to update Multiverse to work with the newest version of Capstone. I have not had time to request these additions be made to Capstone, but if they are added and someone requests it I may have time to update Multiverse to use the newest version.

I tried using the capstone which is mentioned in your readme, but still, the same problem persists. Can you tell me exactly which version of the capstone I need to use?. Thank you!.

If you use the forked version of Capstone linked in the readme, it should work. Can you verify that python is using the correct version of Capstone? If you open a python interactive terminal, then type:
>>> import capstone
and
>>> capstone
What does it print?
